AXLE-LUBRIC'ATOR.

SPECIFICATION forming part of Letters Patent No. 791,697, dated June 6, 19 05.

Application filed e b 4:, 1904:. Serial No. 231,422.

To all whom it may concern:

lubricators in which the oil-passage leading.

to the skein or spindle is provided with a plunger or rod reciprocated by the rotary movement of the vehicle-wheel in order to keep said passage open and allow the proper flow of oil. p

The object of my invention is to provide a simple and effective lubricating mechanism of the character referred to and in which a springprojected plunger is provided with an arm extending outwardly adjacent to the inner end of the wheel-hub, so as to be pressed inwardly by the hub as it moves slightly in or out, and thus reciprocate the plunger to keep the oilpassage clear. These objects I accomplish by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of an axle skein or spindle provided with my improved lubricating means, and Fig. 2 is a longitudinal vertical section thereof. Fig. 3 is a detail view of the plunger. Fig. 4 is a plan view of the skein having my improvements.

A represents an axle skein or spindle formed with the usual annular shoulder a and provided at the outer end with anysuitable hub-retaining device, such as a nut a.

B is the oil-chamber, formed in the upper part of the axle in rear of the shoulder a, and from the bottom of this chamber leads a discharge-passage. b, said passage extending longitudinally through the spindle or skein till its outer end intersects the incline or taper of the spindle and opens therethrough in a somewhat elongated or elliptical outlet Z). Above the oil-level is located a second passage-b which leads out through the outer wall or face of the annular shoulder a.

0 designates the plunger mounted in the oil- -passageb and extending to the outlet 6, so as to clear the same of foreign matter, said plunger being of less diameter than the passage to permit the oil to pass around it. The inner end of the plunger 0 is provided with an operating arm 0, which extends out through the passage 5 adjacent t6 the inner end of the Wheel-hub D. A spring E bears at one end against the inner end wall of the oil-chamber and at its opposite end engages a lug 0, forming part of the inner end of the struction is designed to utilize this longitu- 'dinal. movement of the hubs in actuating the turn the plunger and arm to their normal positions when the hub moves outwardly on the spindle. It will be seen, therefore, that I do away with all cams and like operating attachments for the lubricator by simply utilizing the slight end wise play of the hub.

Having'thus described my said invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with an axle skein or spindle having an oil-chamber and a dischargepassage leading therefrom to the surface of the spindle or skein, of a spring-pressed plunger in the discharge-passage and provided with an operating-arm projecting outward beyond theskein-collar over the inner end of the bearing-surface of the spindle or skein adjacent to the inner end of the hub; said arm to be actuated by the inward movement of the hub in the skein or spindle.

2. The combination with an axle skein or spindle provided with an oil-chamber having a discharge-passage opening at its outer end through the surface of the skein and a guidepassage above the discharge-passage and leading outwardly through the skein-collar, of a and a closure for the oil-chamber, substanspring-projected plunger extending from the tially as described. I0 oll-chamber through sald disharge passage In testimony whereofI afiix my signature in and havlng an operating arm prO ectmg presence of two wltncsscs.

through the guidepassage and beyond the WILLIAM A. J AMESON. skein-collar adjacent to the inner end of the Witnesses: hub; said arm being-actuated by the inward K. H. Du TEESE,

movement of the hub on said skein or spindle, J. N. BURNS.
